Myna Application.sjs Tutorial

The application.sjs file is used to create global variables, methods, or
anything else you want global access to.

You should also use the application.sjs file to operate on the $application
object. This way, you know where your application settings are being set.

You can have multiple application.sjs files as well. For example, you can
have one in your the root folder of your web app, and also have one in a
sub folder. When a script executes, whatever the path of execution, each
applications.sjs file will be included which is in the path from the root down
to the script.

In this application.sjs, we are creating a page object that we can access anywhere
in our application. We can also add to this object in other application.sjs files
in other sub folders. Powerful, but simple!
